H-SEM Operation 3 Operation 3.
Operation H-SEM PURGE 00020pk 10ppm R134A PURGE AIR EMPTY TO FILL PURGE indicates when the monitor is resetting its infrared detector to a baseline of 0 ppm using the air stored in the internal purge-air bag. The purge cycle runs for 10 seconds. The monitor will operate approximately 40 minutes before the purge-air bag needs refilling. When the message "PURGE AIR EMPTY" appears, take the monitor to a clean, fresh-air environment and then press the ENTER button to refill the bag.
H-SEM Operation 3.5 Display Screens 3.5.1 Initial Power Up When the monitor is first powered up, all front panel lights turn ON and a splash screen appears showing the monitor’s current firmware revision level. After a brief moment the Warm Up screen is displayed along with the front panel ON light (green) blinking. BACHARACH WARM UP VERSION x.xx 900 The monitor requires 900 seconds (15 minutes) to warm up; after which, the ON light glows steady and the Data Display screen is displayed. 3.5.

Once a function has been selected, use the Keypad to scroll through the displayed data or to change a parameter associated with that function.
H-SEM FAULTS – Contains records of the last 30 fault events. The most recent event is displayed when the Fault screen is first displayed. After 30 events have been recorded, the newest record overwrites the oldest. Each record lists an event’s numeric fault code (refer to Working with System Faults on Page 10) plus the date and time at which the event occurred. Use any of the Keypad buttons to scroll through the other fault events. Press ESC to return to the previous screen.
Operation H-SEM 3.6 Standby Mode After the monitor has been turned ON and allowed to warm up, the monitor can be placed into a Standby Mode, ready for operation without waiting an additional 15 minutes before using.

Absorption Unit µMole/Liter ∗ Detector Voltage PPM Level – Parts Per Million Level is the current detected gas level, and is the volume concentration referenced to standard temperature and pressure. Average Absorption Unit – This is the optical absorbency. In the absence of gas the absorbency is 0.00000 au. When sampling gas, its value varies proportionally with the gas concentration.
Operation H-SEM 3.12 Entering Custom Refrigerant Calibration Values CUSTOM CAL K^1 xxxx.xxx CUSTOM CAL K^2 yyyy.yyy In addition to the pre-programmed refrigerant gases available for selection, a custom gas can be added by using the CUST K1, K2 & K3 function.
